797 PointsI thought I did, but I guess not...any help?
In User.java, add private fields to store firstName and lastName, and initialize them in the provided constructor. Add public getters for firstName and lastName..
I thought I did exactly that. I even reverted to the ' this.' format. But it wont pass...what am I missing.
Help needed for the User.java
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field topic
public String getTopic() {
return topic;
}
public Forum(String topic) {
mTopic = topic;
}
/* Uncomment this when you are prompted to do so
public void addPost(ForumPost post) {
System.out.printf("A new post in %s topic from %s %s about %s is available",
topic,
post.getAuthor().getFirstName(),
post.getAuthor().getLastName(),
post.getTitle()
);
}
*/
}
public class User {
private String firstName;
private String lastName;
public User (String firstName, String lastName) {
mFirstName = firstName;
mLastName = lastName;
}
public String getFirstName () {
return mFirstName;
}
public String getLastName () {
return mLastName;
}
}
public class ForumPost {
private User author;
private String title;
private String description;
// TODO: add a constructor that accepts the author, title and description
public User getAuthor() {
return author;
}
public String getTitle() {
return title;
}
public String getDescription() {
return description;
}
}
public class Main {
public static void main(String[] args) {
System.out.println("Beginning forum example");
if (args.length < 2) {
System.out.println("Usage: java Main <first name> <last name>");
System.err.println("<first name> and <last name> are required");
System.exit(1);
}
/* Uncomment this when prompted
Forum forum = new Forum("Java");
// TODO: pass in the first name and last name that are in the args parameter
User author = new User();
// TODO: initialize the forum post with the user created above and a title and description of your choice
ForumPost post = new ForumPost();
forum.addPost(post);
// */
}

17,618 PointsmFirstName and mLastName variables do not exist in the User class. You need to use the ones you created (the private fields). In the constructor use 'this' to reference them to avoid name collisions.
